The offset is the distance of where the hub mounting surface is from the center of the rim, it'll be in millimeters. You can grab a ruler and try to measure it but it's probably not going to be that accurate. Check on the inside of the rim, there's normally a sticker that tells you.LikWid696 said:8" up front and 9" rear.....how do i go about measuring my offset? Do i take a ruler and measure from the spokes to the back of the rim?
Oh my fault, I should have looked at your signature. I don't believe HREs would have a sticker stating the rims offset since they're custom made. Most aftermarket Japanese rims do though.LikWid696 said:i looked but couldnt find anything. Im pretty sure they are a 40 offset....they were sinister's old hre rims and im pretty sure he said they were +40. The only difference between 225 and 235 would be the tread width would be a little wider right? So would 235/35/19 on 19x8 with a 40 offset fit in the front without modifications?
